SHADE FOR INCANDESCENT LAMPS.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed August 27, 1906. Serial No. 332.254.

T 0 all whom it may concern:

Be it known that I, EDWARD B. LEwrs, a citizen of the United States,residing at Pacific Grove, county of Monterey, and State of California,have invented certain 'new and useful Improvements in Shades forIncandescent Lamps, of which the following is a specification.

My invention relates to shades for incandescent lamps.

In the present invention my object is to provide, first, a novelshade-holder of simple and inexpensive construction, which can bequickly and easily applied to or removed amp socket and, second, a novelshade of artistic appearance having a new and original construction bothin regard to the shade itself and its manner of attachment to theshade-holder, whereby the shade, being in a plurality of separate parts,may be readily assembled with the shadeholder and, if one of the shadeparts becomes damaged or broken, it can be removed and replaced byanother without disturbing the remaining portions or parts of the shade,beside which my improved construction has the advantage of being lessliable to breakage than it would be were the shade made in one rigidpiece.

In addition to the foregoing objects, the invention contemplates theprovision of a shade, particularly adapted for use with incandescentlamps, the construction of which permits the employment of ieces ofshell, thereby obtaining beautiful lighting effects by reason of thenatural colors of the shell.

The invention is set forth fully hereinafter.

In the accompanying drawings :Figure 1 is a perspective of theinvention; Fig. 2, a plan view showing the shade-holder in section justabove the clamping band; and Fig. 3, a detail section through a portionof the shade and throu h the shade-holder, showing the detachableastenings which secure the parts of the shade to the points of theshadeholder.

In Fig. 1, dotted lines represent an incandescent lamp, its socket, andits conductor cord.

The numeral 1 represents the shell of the shadeholder, said shell havingan inwardly turned upper edge 5 and being provided with a slot 10 in itsside, while its lower portion is formed in a single piece withdownwardly extending outwardly projecting independent points 2 which areof ornamental configuration.

The shade is composed of a plurality of pieces or members 8, which aresecured to the points 2 by detachable nuts and bolts or rivets 4, saidshade members 3 overla ping each other in the manner shown most 0 earlyin Fig. 2, which is accomplished by having the points or prongs 2slightly tilted sidewise. The shade sections 3 may be of any desiredmaterial, but I preferably employ shell for this purpose as it is moreor less transparent and beautiful color effects are obtained by thepassage of the light from the incandescent lamp therethrough. Amongshell which can be obtained cheaply, is the abalone which exists ingreat quantities alon the Pacific coast.

WIthin the shade-holder 1 and secured thereto by a single rivet 7 is aclamping band 6 of springy material which tends to expand. The rivet 7is located intermediate the ends of the clamping band 6 and the ends 8and 9 of the band are bent and extended through the slot 10 in parallelrelation and through them passes a tightening or adjusting screw 11which is screw-threaded into the end or ear 9 and passes loosely throughthe end or ear 8. On account of the freedom of the clamping band 6 atall points except where secured by the rivet 7, the clamping band isparticularly Well adapted to pro erly conform to the lamp socket and cane quickly and easily tightened or loosened, while the overhanging edge 5protects the band 6 and makes a snug and finished fit with the socket ofthe lamp.

The employment of a plurality of points or rongs 2, forming part of theshade-holder, with detachable connections to the shade, has theadvantage of enabling the shade to be securely attached in a removablefashion without employing excess metal, aside from the ornamentalappearance which is obtained and the fact that the separate parts of theshade can be independently detached so that if one part becomes broken,it may be readily replaced at relatively small expense and the necessityfor substituting a complete shade is obviated. 7

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a shade-holder, the combination with a shell having a plurality offlat divergent laterally extending shade attaching parts each formed asone piece andrigidly attached thereto Whose planes lie in generaltransverse relation to the longitudinal axis of the shell, of a shaderigidly connected directly to the said shade attaching parts.

2. vThe combination With a shade-holder having a shell provided withapluralityof shade attaching members constituting eX- tensions of one ofthe edges or margins of said shell and extending in a general transverserelation to the longitudinal aXis of said shell, of a plurality ofindependent shade sections rigidly attached to the respective membersaforesaid. 1 8. The combination with a shade-holder 1 having a shellprovided With a plurality of shade attaching members constituting eX-tensions of one of the edges or margins of said shell and collectivelyflared outwardly from said shade-holder in general transverse relationto the longitudinal axis of said shell, of a plurality of independentshade sections rigidly attached directly to the respective membersaforesaid.

In testimony whereof, I hereunto afliX my signature in presence of tWoWitnesses.
